Aerosol generating and delivery device
First Claim
1. An aerosol generating and delivery device comprising:
- a liquid feed tube having a liquid feed channel with a liquid feed channel exit orifice, an end-wall face and a sidewall, wherein the end wall face between the liquid feed channel exit orifice and a perimeter of the liquid feed tube is substantially normal to a diverting portion of the sidewall of the liquid feed tube; and
a compressed fluid feed channel having a compressed fluid exit orifice, the compressed fluid exit orifice being spaced from the diverting portion of the sidewall, the compressed fluid exit orifice being configured to direct a stream of compressed fluid toward the diverting portion of the sidewall, the diverting portion of the sidewall being configured to disrupt a portion of the stream of compressed fluid, the disrupted portion of the stream of compressed fluid being configured to atomize a liquid from the liquid exit orifice.

Abstract
Particular aspects provide novel atomizers for generating particles over a broad range of MMAD size distributions, the eliminating the requirement for an impaction baffle in generating the desired particle sizes. In particular aspects, the atomization means communicates with a remote particle filter member configured and positioned to provide for particle size filtering. In additional aspects, the atomization means communicates with a particle dispersion chamber suitable to impart a desired particle flow pattern to particles within and exiting the dispersion chamber. In further aspects, the atomization means communicates with a nasal, ocular, oral or ‘vicinity’ adapter. The novel devices provide for targeted (e.g., nasal, ocular, oral, local vicinity), systemic, and/or topical delivery of an atomized liquid (e.g., via the nasal cavity, olfactory region, and mouth). Further exemplary aspects relate to aerosolization and delivery of perfume, fragrance, essential oil or cosmeceutical agents and the like.
